IMPROVEMENT IN MACHINERY FOR MAKING CUBE SUGAR.

Specification forming part of Letters Patent No. 208,522, dated October1, 1878; application filed April 12, 1878.

To all whom it may concern:

Be it known that I, WiLLIAM JASPER, of the city and county of SanFrancisco, in the State of California, have invented a certain new anduseful Improvement in Machinery for Making Cube Sugar, which inventionis fully set forth and described in the following specification and theaccompanying drawing.

My invention relates to machines for cutting and forming sugar intocubes from a slab or block 5 and it consists in an improved mechanismfor pressing the cubes before the cutterplate is withdrawn or raised,and for holding them upon the tray while the cutters are being raised.

The object of my invention is to give a uniform density to the sugarcubes, andtq produce them from the slab or block with sharp and squareedges and surfaces. 0

In the drawings herein referred to, Figure l is a side eleva-tion, inperspective, of the cutter and pressers, showing the manner in whichthey are both arranged in the machine-frame. Fig. 2 is a detail view, inperspective, of the cutters and the pressers. Fig. 3 is a verticalsection through these parts.

The cutter -plate A is formed of a set of blades, a a, set across eachother and forming rectangular spaces of the size required for the cubes.This`- plate is supported by a crosshead, B, within the frame, and isreciprocated between the uprights C C by the lever D, that is actuatedfrom a driving-shaft of the machine or other mechanism with which thismy invention is combined.

The plate E, arranged above the putter, carries the pressers F, whichare formed of a series of rectangular blocks, secured upon or to theends of short vertical rods projecting from the bottom of the plate E,and corresponding in number and size to the rectangular spaces betweenor inclosed by the cutting-blades a a. Within these spaces the presserslit and slide closely. These pressers are supported from the cross -headCr, and are reciprocated, by means of the lever H, from a proper shaftor moving part of the machine.

The levers D H are actuated either by means of arms on a rock-shaft,connected thereto by rods, or by cams and lifting-rods, or any similarmechanism, by which the cutter and the presser are moved to cut thesugar, to press the cubes while they are held between the blades of thecutter, and to hold them steady upon the tray against any movement whilethe cutters are moving up out of the sugar.

These motions required to properly operate the pressing mechanism takeplace in the following manner: When the cutter A is brought down uponthe slab of sugar presented to it on the tray or plate Z, and is pressedthrough to separate the mass into cubes, the pressers F are moved downfor a short distance with a strong pressure while the cutters areholding the cubes, and a compression of the so-formed cubes takes place,by which their surfaces are rendered smooth and even and the edges sharpand clean; and while the pressers are still bearing upon the top of theformed cubes the cutters begin to move upward out of the sugar until,after reaching a certain height from the bottom of the cubes,sufficiently to clear them from the adhering sugar and cause them tomove smoothly out from between the cubes, the cutter A strikes thepresser -plate E, and in rising lifts it, with its pressers, free fromthe cubes, which are left perfectly formed and detached upon the plateZ, ready to be removed from the machine to the drying-room.

I do not claim, broadly, the pressing of the cubes of sugar in the moldsafter being cut from a slab, nor do I claim in this application thebroad combination of a plate to support the slab of sugar, and a seriesof parallel and perpendicular cutters reciprocated above such plate andworking over pressers, which force the cubes from the cutters when thesame are raised, since such combination is shown in patent granted to meAugust 14, 1877, and numbered 194,244; but in that patent the pressersare not forced down to compress the sugar after the cutters have dividedthe slab into cubes, and by this change in the combination I am enabledto produce cube sugar of uniform density and with sharp and squareedges, as before described.

Having thus fully described my invention, what I claim therein as new,and desire to secure by Letters Patent, is-- A cube sugar machinewherein are com billed a plate, Z, for supporting' a slab ofsucutting-frame and presser-plate, substantially gar, the cutting frameA, reciprocating: veras described and shown.
